Achieving carbon neutrality requires major changes in the chemical industry. In order to achieve carbon neutrality, it is necessary to transform the supply chain, which has hitherto been dependent on fossil resources, into a sustainable supply chain. This is both a big challenge and a big business opportunity. Therefore, in this session, following the previous INCHEM TOKYO exchange meeting, we will introduce the latest technology and hold a talk session with the theme of "social implementation of hydrogen supply chain".
